Meanwhile, discussing signing up for the new series, Catherine said this week: "I am a huge fan of the show. I’ve tried to watch it as much as I can since the first show. But I also can’t dance. I went to drama school but I never had the confidence to take part in the dance classes – often I’d avoid them completely.
